Improvement in umbrellas

'runners v. NoErrE, or BROOKLYN, New YORK.

lMPFtOVEMENT IN UMBRELLAS.

Speciiieniion forming parl of Letters Patent No. LMEJS, dated August il, 1.564.

To all whom, it nto/y concern:

Be it known that I, .FRANCIS V. NOETTE, of Brooklyn, in the county of Kings, inthe State ot' New York, have invented a eertan new and useful Improvement in the Construction of the Frames of Umbrellas and the like Structures; and I do hereby declare that the ibllowing is a iull and eXactdescription thereot'. n

My improvement relates to the part where the spreading ribs and -stretcliers or braces arejoined to the main standard; and it consists in the use of sockets, cheaply formed, of thin tubing in`two parts, one within the other, within one end of each spread, and properlyv shaped to coniine the ends ot the ribs or stretchers between them, in the manner to be hereinafter described.

The accompanying drawin form a part of this specification.

Figure 1 is a side view 5 Fig. 2, atop view; Fig. 3, a central vertiealsection, Fig.4, a crosssection on theline S S in Fig. 3; Fig. 5 a crosssection on the line T T in Fie'. 3 5 Figs.' 6, 7, and 8, difierent forms of the ends ot' the ribs and stretchers, either ot' which form of ends may be used with my invention. Fig. 9 is a vertical section on a larger scale, showing two modes ot putting together the parts, either of which modes may be used with my invention.

Similar letters ot' reference indicate like parts in all the lignres.

My invention is applicable to umbrellas ot' all kinds, parasols ot' all kinds, and all the varieties ot sunshades and analogous articles ot' whatever name, asalso to any kind ot' tent or other structure which may require aframe adapted to fold in a. similar manner.

The purpose ot myinvention is to cheapen the construction and facilitate repairs, and to produce a stronger and more durable structure than that made in the ordinary manner.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation bythe aid ot' drawings and ot' the letters of reference marked thereon.

A' is central sta it' or handle of the um brella. y

B l5, &c., are the ribs or a: mi, which are to be folded and ext-ended; and G C, Soc., are the stretchers or braces by which the ribs D are operated. These parts are, constructed in the ordinary manner, except that the ends of the ribs B and stretchers G, which are hinged to the standard A, are formed as shown in one ofthe Figs. 6, 7, and 8, or in some analogous manner, so as to present a large part or head at that end.

D and E are half-sockets, adapted to embrace and retain the heads of the arms or stretchers, allowing the latter to turn freely, but notte escape, when the parts D and E are secured together. When the parts D and E are separated1 the heads of' the ribs B and stretchers C may be easily removed and replaced to admit ot'repairs. Each et' these halt'- sockets is formed of a short length of sheet brass or copper tube. 'lhe tube may be made oi' sheet metal by bending it around and brazing the edges together, so as to t'orm al tube; or it may be made by any of the processes ior producing tubes from ingots, so as to possess a uniform thickness and character throughout. rlhe tube D is originally ot' such diameter as to tit closely around the standard A. The tube F is originally larger. rlhe ends both of D and E, which are to receive the heads of the ribs or stretchers, are expanded and formed in the shape represented by spinning it in a lathe, or striking up in dies or otherwise, either at a single operation, or by several steps, properly annealing it between each oparation, so that when the parts D and E are properly fitted together, a semicirci'dar groove, d, in one shall match against a corresponding semicircnlar groove, c, in the other to forni hollow ring adapted to hold the heads b or e, and allow them to turn. (Sec Fig. 9.) Portions ot' the end of the inner tube, D, are then cut out by suitable tools, so as t-o form mortises d, (see Fig. 1,) in each of which mortises the neck of a rib or stretcher may turn while itshead is retained in the cavity formed by the grooves d and c, all of which lwill be understood with little difiicult y from the drawings. 'lhe full lines show the position of the ribs and stretchers when the umbrella is open or extended. The dotted lines show their posi.- tion when the umbrella is closed. The device l) and E, used at the upper end of the standard to hold the ribs B b, is placed inverted relatively to the corresponding device used to hold the stretchers C c, for obvious reasons. The lowerxuost is made longer, and should fit easy around the standard A, so as to slide freely thereon, and be conveniently operated,y and held 1n the ordinary manner. The transverse pin G passcsthrough holesin both the tubes D and E at the upper end ofthe standard A,nnd holds them tightly together orreleases them, to 'allow the contained arnis B b to be removed and inserted. A male screw-thread on the tube D and a female screw-thread on the `tube E perform @corresponding function for the lower device, to allow the contained stretchers C c to be held and released.

To fit my device when made in the lowerniost or screw forni, I seize the outer tube, E, with a pipe-Wrench or analogous tool., and turn it around upon the inner tube, D. In the lower end of Fig. 9 the parts are represented as so constructed and widely separated.

Additional tubes maly be brazed or other- Wise litted upon either of the tubes D or E at tially in the manner and-for the purpose herein set forth. i l
